What do customers need to consider before the measurement?
For comparable measurement results, comparable measurement conditions must always prevail, as bioimpedance analysis is a sensitive measurement method. If you measure yourself one time before a sumptuous lunch and the other time directly afterwards, your measurement will be falsified. So always keep the following in mind for precise and comparable measurements with your customers:
The menstrual cycle should be taken into account when choosing the time of measurement. Water retention can occur during or shortly before menstruation, which can affect the measurement results.
It is best to always measure at the same time (e.g. in the morning after breakfast). Initially always measure your height and then only use this measured value. It is best to take the measurement before a meal or a few hours after. Do not drink large quantities before the measurement and empty the bladder before the measurement. Alcohol should be avoided 12 hours before the measurement. Always measure before training. Never measure after or during training. Likewise, no intensive training should have taken place the day before.
Illnesses and medication can affect the measurement.

What factors can influence the measurement results?
In addition to the optimal measurement conditions, there are other factors that can influence the measurement result of the bioimpedance analysis. These should always be taken into account in order to ensure the most accurate and meaningful analysis possible:
- Hydration status: An unbalanced water balance can distort the measured values. It is therefore important that the test subject is neither dehydrated nor over-hydrated.
- Clothing and jewelry: If possible, the measurement should be carried out in light clothing and without metal objects (e.g. rings, watches or necklaces), as these can influence the impedance values.
- Skin temperature: Cold or very warm skin can change the electrical resistance. Make sure that the test person is in a normal, comfortable temperature range before the measurement.
- Posture and positioning: During the measurement, the test person should stand or lie down in a relaxed position – depending on the type of device. Incorrect posture or movement can affect the measurement result.
- Long-term changes: Regular measurements not only show short-term fluctuations, but also help to identify real progress. It therefore makes sense to always consider the results in the context of a longer time series.
- If all these factors are taken into account, you can make optimum use of bioimpedance analysis to provide your customers with precise and reliable results.
